SPECIFICATION forming part of Letters Patent No. 552,030, dated December 24, 1895. Application filed January 14,1895. Serial No. 534,848. (No model.)

To all whom it may concern:

Be it known that I, Enoon S. YENTZER, a citizen of the United States, residing at Ottawa, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Machines for Sewing on Buttons; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for sewing buttons to clothes, fabrics and other articles; and it consists, first, of a sewing mechanism, combined with a button holding and carrying device havinga primary and secondary slide, a supplemental operating socket-plate secured to the primary slide for actuating the said primary and secondary slides, an eccentric operating in the socket-plate, and means for operating the said eccentric, whereby a button may be presented in a proper manner to the sewing mechanism and sewed on garments, as hereinafter described.

It consists, secondly, of an ordinary sewing mechanism combined with a button holding and carrying device having a primary and secondary slide, the primary slide being capable of a longitudinal and lateral movement and the secondary slide being capable of a longitudinal movement only, a socket-plate pivoted to the primary slide, an eccentric for operating the socket-plate, auxiliary means for securing the socket-plate to the primary slide, whereby the latter is capable of having both lateral and longitudinal movement,and means for securing the slides positively together, so that they will be capable of having longitudinal movement only, and means for operating the eccentric, socket plate and slides, the construction and operation being such that two-hole as well as four-hole buttons can be sewed on.

It consists, thirdly, in a machine for sewing on buttons, of the combination, with an ordinary sewing mechanism, of a button holding and carrying device having a combined button-holder and spring resser-plate, which is spring-acting in itself and aids in supporting a button and simultaneously pressing the goods, and means for operating the button holding and carrying device.

It consists, fourthly, in a machine for sewing on buttons, of the combination, with an ordinary sewing mechanism, a button holding and carrying device, and an eccentric for operating the same, of a pinion secured to the shaft of said eccentric, a gear-wheel meshing with said pinion, a yoke adapted to engage and operate said gear-wheel, and a lower shaft of the machine provided with means for operating the yoke.

It consists, fifthly, in a machine for sewing on buttons, of the combination, with an ordinary sewingmechanism, a button holding and carrying device and an eccentric for operating the same, of a pinion secured to the shaft of said eccentric, a gear-wheel meshing with said pinion and provided on one of its faces with an annulus having a depression, means for actuating the gear--wheel, a spring-actuated lever pivoted to the under side of the machine and connected to a braking and clutching mechanism and adapted to bear with one of its ends upon the annulus'and engage the depression on the same for operating the braking and clutching mechanism.

It consists, sixthly, in amachine for sewing on buttons, of the combination with an ordinary sewing mechanism and a button carrying and holding device having a primary and secondary slide, of an eccentric for operating the said slides, provided with an operating handle by which it can be manipulated by hand independently of the other operating parts of the machine, and means for actuat ing the eccentric; and it also consists in certain other novel constructions and arrangements of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of my improved machine for sewing on buttons, a part of the work-plate being removed to show the operating mechanism beneath said plate. Fig. 2 is a bottom plan View of the machine, the lower shaft of the same being broken away to more clearly show the gearing for operating the button holding and carrying device.

Fig. 18 is a detail bottom plan view of a modified form of mechanism for operating the button holding and carrying device. Fig. 19 is a detail view of the gear-wheel shown in Fig. 18. Figs. 20 and 21 are views similar to Figs. 18 and 19, but showing another modified form of gear-wheel.

Arepresents a work-plate, B a lower shaft, and O a needle, of a machine provided with an ordinary stitching and sewing mechanism. D is a button gripping and holding device. E is a spring, and E a spring presser-plate; F, a plate for carrying the goods to which it is desired to sew buttons. G is a primary slide to which the parts D, E, and F are secured, all of which together with a secondary slide H constitute a button-carrying device.

I is an eccentric for actuating the button holding and carrying device; J, apinion; K, a gear-wheel meshing with the pinion J and operating the said pinion and eccentric I.

L is a yoke for rotating the gear-wheel K, and M is a collar secured to the shaft 13 and provided with. a projection on for engaging the yoke L. 1

The primary slide G is preferably formed of a flat rectangular piece of metal provided with laterally-extendin g guide-pieces g,which work in guideways h, on the upper face of the secondary slide II, thus permitting of a lateral movement of the primary slide G. The secondary slide H is confined between guide-pieces 7L, preferably secured by screws to a base-plate H, which is also secured by screws or otherwise to the upper surface of the work-plate A of the machine, the secondary slide H being free to move longitudinally between the guide-pieces h. It will thus be seen that the primary slide G is capable of both lateral and longitudinal movement. The secondary slide H is of approximately rectangular shape, having laterally-extended portions on which the guideways h are formed.

To the upper face of the primary slide Gis pivotally secured a socket-plate G by means of apivot-screw g, passing through said plate and screwing into the primary slide G. The other end of the socket-plate G is provided with a socket G in which the eccentric I works as it revolves, carrying with it said end of the plate in the different positions it assumes. The socket-plate G is provided with a hole near the socket G through which a screw maybe introduced, as'at g and screwed into a threaded hole in the primary slide G, thereby securing the socket-plate G rigidly to the said primary slide and preventing its having any movement independently of the primary slide. When it is desired to sew on a button having four holes and it is necessary to carry the button in the lateral and longitudinal directions, the socket-plate G can thus be fixedly secured to the primary slide G by inserting a screw at g and thereupon the same motion is imparted to the primary slide G that is received by the socket-plate G from the rotation of the eccentric I but when it is only desired to sew on buttons having two holes it is not necessary to impart a lateral motion to the primary slide G, and said motion may be dispensed with by removing the screw from g and placing it, as at g in holes provided in the primary slide G and secondary slide 11, so that the said slides are secured together and the primary slide is limited to the movement of the secondary slide, while the socket-plate G is left free to vibrate on its pivot g, and thus accommodate itself to the various positions of the eccentric and yet be capable of imparting the necessary longitudinal movement to the primary slide carrying the button -holder. These arrangements of the parts will be better understood by reference to Figs. 6, 7, and 8 of the drawings.

The eccentric I, which moves the socketplate and the slides, is mounted upon a shaft 1, its lower ends extending below the workplate A and being secured to the pinion J. The eccentric I may be of any suitable shape,

it being shown in Figs. 1, at, 5, 6, 8, and 13 as having a circular form, in which case the socket G of the socket-plate G is also made in form of a circle to fit the same.

In Figs. 7 and 9 I have shown a modified form of the eccentric, it being slightly fiattened on three sides, giving it generally a triangular shape with rounded corners. hen this form is used, the socket G is preferably of a square shape, this being the best form for fitting the eccentric snugly. The circular form of the eccentric is a desirable form, for the reason that the motion imparted to the button holding and carrying device is even and smooth. The form of eccentric shown in Figs. 7 and 9 is also a desirable one, since it imparts very decided and distinct move ments, and is therefore more sure to move the button accurately to the positions where the needle 0 can pass through the holes of the button.

In using the circular eccentric, when the machine is running at a rapid speed, there is a tendency for the eccentric to be thrown slightly beyond the positions in which it should pause in its intermittent movement, and thus there is danger that the button may be carried a trifle too far and being struck by the needle, thereby causing damage, instead ofbeing moved just right for the passage, safely and accurately, of the needle through the hole of the button. \Vhen using this form of eccentric, therefore, I employ a friction-clamp, which, when properly adjusted, overcomes the liability .of the difficulty above referred to. As shown in the drawings, the friction-clamp is preferably formed of a fiat spring G of a semicircular shape, secured at its central portion by a screw or otherwise to a projection G on the upper surface of the socket-plate G, and its ends being provided with friction-pieces g adapted to bear upon the periphery of the eccentric. In order to regulate the pressure of the spring G a V-shaped follower-piece G is mounted upon the socket-plate G, the fingers of the bifurcated end of which bear upon the spring G the force with which it presses upon the spring G being regulated by a set screw g passing through a slot g in the follower-piece G and screwing into the socketplate G.

To make it possible to sew on buttons having holes of varying distances apart the eccentric I is mounted upon its shaft 1 in such a manner as to be adjustable to a greater or less eccentricity, so as to impart a greater or less movement to the button holding and carrying device according as buttons having holes far apart or near together are being operated upon.

To accomplish that adjustment whichis preferred, the eccentric I is provided with a vertical rectangular slot 1 of suitable length to allow of considerable range of adjustment, through which the shaft I passes, the said shaft being squared upon the portion of its length contained within the slot I and thus adapted to actuate the eccentric in whatever part of the slot it may be. A screw 1 passes diametrically through the eccentric I longitudinally of the slot l and through the square portion of the shaft I. The screw I is only threaded on that part of its length which extends through the slot 1 the threads engaging corresponding threads in the shaft 1, the ends of the said screw which are contained in the solid part of the eccentric I being smooth, so as to enable it to be revolved without changing its position longitudinally in relation to the eccentric. A pin 2', passing vertically through the eccentric I, engages an annular depression in the head of the screw I and retains it in its proper position without preventing it from being turned. When the screw I is rotated, its threads engaging the threads of the shaft 1 will therefore move the eccentric I to a greater or less eccentricity accordingly as the screw 1" is turned one way or the other. A small screw 71 in the eccentrio bears with its end upward on the shaft 1 and when tightened serves to hold the cocentric in the desired adjusted position. The screws I and Q1, being above the plane of the socket-plate G, are always accessible, and can therefore be adjusted at any time without any inconvenience or difficulty.

The shaft 1 extends above the eccentric I and has a bearing in an L-shaped guide-standard secured to the base plate H, being steadied and braced thereby in its operation. To the upper end of the shaft I a thumb-nut 1 1s secured, by means of which the shaft I and eccentric I may be turned by hand independently of the operating mechanism. This is a very important construction, as will be hereinafter shown.

Beneath the work-plate A of the machine and meshing with the pinion J on the lower end of the shaft 1 is the gear-wheel K, held in operative position on the under face of the work-plate A by a screw-bolt 7c. The gear wheel K is engaged and operated by the yoke L in a suitable manner, the said yoke being also held in position by the screw-bolt 7c. The fingers Z Z of the bifurcated end of the yoke L are bent upwardly and downwardly, extending one on either side of the lower shaft B of the machine, and are thus adapted to be operated upon by the projection m of the collar M, secured to the shaft B. As the projection m revolves with the shaft B, it impinges first uponone finger of said bifurcated end and then upon the other, thus imparting a vibratory movement to the yoke L, the said yoke being adapted to engage and actuate the gear-wheelK when it is vibrated in one direction but not in the other, so that the gear-wheel is rotated in only one direction.

In order to enable the yoke L to engage and operate the gear-wheel K, theyoke is preferably provided with a spring-pawl Z shown in Figs. 1, 2, 5, 13, 15, 1G, and 17. The pawl l is in the form of a flat spring secured at one end by a screw or otherwise, the other end being free. The free end is provided with a pin Z, preferably screw-threaded, so that it may be removed when worn and be replaced by a new one. The end of the pin Z is adapted to extend through an aperture in the yoke L and engage a series of holes 7c in the gear-wheel K, the said end of the pin 1 being beveled, as shown in the drawings, so that when the yoke is vibrated in one direction the pin will catch in one of the holes and thereby move the gear-wheel K, but on the return stroke will be adapted to slip out of that hole into another, and so on. A retaining spring-pawl Z is secured to the under side of the work-plate A similar to the pawl Z and so placed as to be capable of engaging the series of holes 76 in the gear-wheel K and by the beveled edge of its pin Z permit the gear-wheel to be rotated in the desired direction by the pawl Z on the yoke L, but to hold it from moving back again when the pin Z of the pawl Z is slipping into another hole. By this construction it will be seen that the operation of the machine and its lower shaft 13 accomplishes the rotation of the gear-wheel K, and thereby the eccentric I, by an intermittent or step-by-step movement, the said parts always turning in one direction.

In Figs. 18,19,20 and 21 modified forms of gear-wheels are shown, which, together with slightly-different forms of the actuating and retaining pawls, accomplish the same result as the construction above described, in a desirable and satisfactory manner. As shown in Figs. 18 and 19, a gear-wheel 70 may be used having upon its under surface a ratchetdisk provided with ratchet-teeth 70 on its periphery. In this form of construction the spring-actuated pawl on the yoke is adapted to engage the ratchet-teeth 70 as is also the spring-actuated retaining-pawl. As shown in Figs. 20 and 21, a gear-wheel K may be used having radial ratchet-teetlrk formed upon its under surface, simple fiat springpawls with engaging ends being used to actuate and retain it.

From the above description it will be noticed that the eccentric I receives its motion from the gear-wheel K through the pinion J on the lower end of the shaft I, so that if the gear-wheel K is adapted to move the pinion J a certain number of degrees, which is a half or a third or a fourth of one complete revolution between every pause it makes in its intermittent movement, the eccentric will be moved correspondingly and thereby throw the primary slide in two, three, four, or more diiferent positions at each revolution, thus presenting to the needle 0 buttons having either two, three, four, or more holes, so that the needle will pass accurately through the holes and sew on the buttons. I11 illustrating this construction, the drawings show the parts adapted for sewing on two and four hole buttons. As shown the pinion J has twelve teeth, so that if the gear-wheel K operate upon three teeth it willmove it ninety degrees, or one-fourth around, and if upon six teeth it will move it one hundred and eighty degrees or one-half around. It will also be plain from this that if the gear-wheel K were adapted to operate upon four teeth of pinion J it would move it one hundred and twenty degrees or one-third around for sewing on three-hole buttons.

In the forms shown in Figs. 1,2,3,5,13,15,16, 1'7, 18, and 19 the holes 70 on the one and the ratchet-teeth 70 on the other are arranged opposite every three teeth on the periphery of the gear-wheel K, the said gear-wheel being provided with a multiple of that number of teeth, so as to make the arrangement come out even, the number shown being seventy-two. By this arrangement when the yoke L is reciprocated so as to actuate the gear-wheel K one hole or one ratchet-tooth the gear-wheel will be moved the distance of three teeth and will engage three teeth on the pinion J, producing the desired result. By this construction a button having four holes will be sewed on by stitches arranged in a circuit from hole to hole around the button. A very desirable way to sew on buttons having four holes is to arrange the stitches between opposite holes across the center of the button. To accomplish this and also the sewing on of twohole buttons it is necessary to move the eccentric half-way around at each step. One of the fingers Z of the bifurcated end of the yoke L is provided with a metal piece L, secured thereto by a set-screw. This piece L is turned back out of the way, as shown in most of the views in the drawings, when it is desired to sew on four-hole buttons with the step-by-step stitch around the circuit of its holes, but when it is desired to sew on twohole buttons or four-hole buttons across the center, the piece L is turned forward and held there by the set-screw, as shown in'Fig. 17, so that when the projection m revolves it will impinge upon the said piece instead of the finger l of the yoke L and will move the said yoke twice as far as before or two holes or ratchet-teeth of the gear-wheel K K, and thus move the pinion J and eccentric I halfway around at every step. In sewing on fourhole buttons in this manner, after sewing between two opposite holes a suflicient number of stitches, the eccentric is turned one-fourth around independently of the machine by taking hold of the thumb-nut I on the shaft 1 by the hand. In this way one of the other two holes of the button which have not been operated upon will be brought under the needle 0, and the machine will then proceed to stitch between those two holes, producing what may be termed a cross-bar stitch, which is the way buttons are usually sewed on by hand and is very desirable.

WVhen nothing but two-hole buttons are to be sewed on and only a reciprocating movement of the button holding and carrying device is necessary, the lateral movement and the friction consequent thereupon may be stopped, as has been fully explained hereinbefore, by changing the screw from the holes in the slides at g to those at 9 The step-by-step movement of the gearwheel K may be steadied by a friction-clamp, as K having a friction end adapted to bear upon the under face of the said gear-wheel. Upon the upper face of the gear-wheel K is an annulus K preferably made of a separate piece of metal and secured to the face of the gear-wheel by screws or otherwise and having in its periphery a depression K Pivotally secured to the under side of the work-plate is a lever N, one end of which is hooked and adapted to enter the depression K of the annulus K The hooked end of the lever N is pressed against the periphery of the annulus K by a spring 12, secured to the work-plate A, and when the gear-wheel K with its annulus is revolved completely it is forced therebyinto the depression K The other end of the lever N is provided with a downwardly-extending arm 71-, having a notched or hooked end if, adapted to engage and hold the end of another lever O, pivoted to a depending flange of the work-plate A, the other end of said lever 0 being pivotally connected to an upright arm P. The arm P extends up through a guiding-opening in the work-plate A and connects by its upper bifurcated end 1) with a braking and clutching arm Q, formed in the usual manner with a friction -.bearing for impinging against the hand-wheel of the machine to stop its revolution,and thereby the operation of the machine, when desired, and adapted by one of the ends to force the power-receiving pulleyinto frictional engagement with the said hand-wheel and thereby operate the machine when the brake is not in operation. The other end of the arm Q can be depressed by a foot-lever (not shown) by means of a rod connecting the two. A spring 19', secured to the lower end of the arm P, holds the clutching device normally out of operative engagement, at the same time applying the brake. When the clutch is forced into operative engagement and the brake released by depressing the footlever, the end of the lever O is forced into engagement with the hooked end n of the lever N, which will hold the parts in that position until the gear-wheel has made one revolution, when the other end of the lever N will spring into the depression K of the annulus K thereby releasing the lever O and allowing the brake to be applied and the frictionclutchtobe released for stopping the machine. One revolution of the gear-wheel K allows of suflicient number of stitches being taken to securely sew on a button.

The primary slide G carries a button-holder D of suitable construction to hold and present to the needle in a proper manner buttons of various sizes. In carrying out this part of my invention a plate R is secured to the front end of the primary slide G, having upturned side flanges rr, to which a j aw-carrying plate S is pivotally attached in such a manner that it may oscillate, the said plate being provided with flanges for guiding the movement of the parallel movements, and thus are enabled to hold buttons of any size that can be placed between them with great firmness, and the large ones as effectively as the smaller ones. The slides of the gripping-jaws are provided with projections or pins 3 s, which engage slots 5 s in a plate S pivoted between the two pins 8 s on the plate S, so that by moving one jaw the other will be moved in the opposite direction. A coiled spring S is attached to a projection on the plate S at one end and to one of the guiding-flanges of the plate S at the other end and normally keeps the jaws closed. The gripping-jaws S S are each provided with concave surfaces 8 s to fit upon the periphery of the button and extending flanges s s upon their upper faces to prevent the button from being accidentally disengaged in any way.

Fastened to the forward end of the primary slide G and extending under and bearing on the under side of the rear end of the oscillating plate S is a flat spring E for forcing that end up and thus keeping the forward part of the device normally down and holding the goods and button in proper position. A spring presser-plate E is fastened to the forward part of the oscillating plate S and extends under the gripping-jaws S S and its under surface is roughened, as at E, Fig. 23,

to firmly hold the goods placed under it. The

spring presser-plate E forms a part also of the button-holding device, the button resting upon said plate when in position between the jaws S S In order to move the goods over the workplate with the buttonholding device, the plate F is secured to the under side of the plate R, which carries the button-holding device and extends forward under and beyond the presser-plate and gripping-jaws, so that the goods are carried between the said plate F and the presser-plate E.

In order to open or retract the gripping jaws to insert or remove a button, a bellcrank lever T is pivoted to a standard T, extending up from the work-plate, one end of said lever extending downwardly and engaging the gripping-j aw S and the other adapted to be operated by an arm u, extending from the presser-foot standard U, so that when the presser-foot standard is raised in the usual way it-will retract the jaw S and thereby the jaw S The bell-crank T is provided with an upwardly-extending arm 15, by which the jaws may be retracted by hand without moving is 5mm any other mechanism, if so desired. The arm at is also adapted to raise one end of a lever 7 pivotally secured to an extension of the upturned flange r of the plate R, the other end of the lever 0' bearing upon the rear end of theplate S and adapted to press it down, and thus raise the gripping-jaws and the presser -plate. The parts are so arranged that upon raising the presser-foot standard U the gripping-jaws will be firstretracted and then by continuing the upward movement of the standard U the jaws and presser-plate will be lifted, so that the goods and buttons may be properly put in place or taken away.

In Fig. 22 a modified form of gripping device is shown, in which the projections on the slide ends of the gripping-jaws are engaged by the bifurcated ends of the bell-crank levers S S, pivoted to the oscillating plate, the one moved and operated by the other by means of a pin-and-slot connection at their other ends. The levers S S are drawn together normally by a coiled spring and the jaws thus closed. The bell-crank T engages an I-shaped projection S on the lever S and is thereby enabled to retract it and open the gripping-jaws.

In putting the goods-and button in place it is very desirable to have the use of both hands for the purpose, and I therefore pro vide the machine with the usual knee-presser and connecting parts, consisting of the knee presserleverV, (shown in dotted lines in Fig. 1.3,) engaging a vertical rod IV and thereby operating the levers IV 7 for the lifting of the presser-foot standard U.
